Use VERBOSE to See What Your EMS Commands Do

"Sometimes you need to know exactly what EMS does to help track down a problem, perhaps to provide information to Microsoft support to help them figure out what's going on in your Exchange deployment. You might just want to know what's happening when you execute a command. In either case, you can add the –Verbose parameter to a command to have PowerShell generate details of exactly what it does as it proceeds."
